JERSEY CITY — A 23-year-old Jersey City man charged with the 2015 vehicular homicide of an 8-year-old boy is facing new allegations of witness tampering for allegedly threatening a witness slated to testify at his trial.

Shaquan Roe, of Bidwell Avenue, is charged with causing the death of Jermaine Woodward Jr., who was struck by a car on Bostwick Avenue in Jersey City on June 28, 2015. The boy suffered multiple broken bones and he died at the hospital the next day.

Roe wasn’t arrested until May 2016 after a grand jury indicted him on the vehicular homicide charge. However, because he was arrested prior to the state’s Criminal Justice Reform law taking effect, he was released from custody after posting a $75,000 bail bond.

However, in September 2017, Roe “approached the witness on the street and threatened physical harm against him, in retaliation for the witness’ cooperation in the state’s case,” according to a criminal complaint detailing the new charges.

A warrant for Roe’s arrest on the witness tampering charge was signed last Wednesday and he made his first appearance on the charge Tuesday afternoon in Criminal Justice Reform Court in Jersey City via video link from Hudson County jail in Kearny.

But the witness tampering allegations are not the only charges that Roe has faced while awaiting his trial, authorities say.

He was charged with criminal restraint, assault and theft following an April 4, 2017 incident in which he allegedly forced a woman into his vehicle, choked her, slapped her numerous times. He then took the woman’s cell phone and prepaid credit card worth $180, according to a criminal complaint.

Then in June, Roe was accused of entering a residence through a window and stealing a cell phone, the court document alleges.

Finally, he was arrested Dec. 12 on the charge of conspiracy to distribute cocaine. At the time of his arrest on the drug charge, he had not yet been apprehended in connection to the two prior incidents.

When Roe appeared in court Tuesday, the state moved to detain him through the course of his prosecution. A detention hearing is scheduled for Friday before Hudson County Superior Court Judge Paul DePascale.

When arrested on the drug charge prosecutors said they would seek revocation of Roe’s bail on the vehicular homicide charge. That hearing was set for Jan. 5, but was postponed, making Roe’s upcoming detention hearing relevant rather than merely procedural.
